"Don't theorise," Eldred snapped. "We've got a good day's work before we start. And there is no time to be lost." "Luncheon first," Sir Edgar suggested, "served in here. It will be plain and cold; but, thank goodness, there is plenty of it. My word, after that awful darkness what a blessed thing light is once more!" * * * * * Two hours after midnight the doors of the workshop were pulled away and the aerophane was dragged on its carriage into the garden. The faint glimmer of light only served to make the blackness all the thicker. The three men waved their hands silently to Cynthia and jumped in. A few seconds later and they were whirred and screwed away into the suffocating fog. IV. London was holding out doggedly and stolidly. Scores of houses watched and waited for missing ones who would never return, the streets and the river had taken their toll, in open spaces, in the parks, and on the heaths many were shrouded. But the long black night held its secret well. There had been some ruffianism and plundering at first. But what was the use of plunder to the thief who could not dispose of his booty, who could not exchange a rare diamond for so much as a mouthful of bread? Some of them could not even find their way home, they had to remain in the streets where there was the dread of the lifting blanket and the certainty of punishment with the coming of the day. But if certain houses mourned the loss of inmates, some had more than their share. Belated women, frightened business girls, caught in the fog had sought the first haven at hand, and there they were free to remain. There were sempstresses in Mayfair, and delicately-nurtured ladies in obscure Bloomsbury boarding-houses. Class distinction seemed to be remote as the middle ages. Scotland Yard, the local authorities, and the County Council had worked splendidly together. Provisions were short, though a good deal of bread and milk had with greatest difficulty been imported from outside the radius of the scourge. Still the poor were suffering acutely, and the cries of frightened children were heard in every street. A few days more and the stoutest nerves must give way. Nobody could face such a blackness and retain their senses for long. London was a city of the blind. Sleep was the only panacea for the creeping madness. There were few deeds of violence done. The most courageous, the most bloodthirsty man grew mild and gentle before the scourge. Desperate men prowled about in search of food, but they wanted nothing else. Certainly they would not have attempted violence to get it. Alarmists predicted that in a few hours life in London would be impossible. For once they had reason on their side. Every hour the air, or what passed for air, grew more poisonous. Men fancied a city with six million corpses!
